That would be a DB25 RS232C port. It can be used for two ports in one but is typically wired with no more than whats in the smaller DE9 version.http://www.aggsoft.com/rs232-pinout-cable/RS232.htm
The 9 pin version is DE9. There is no such thing as a DB9 connector. That's the E size. A VGA video port is a DE15 or HDE15 *not* a DB15. (H for High density.) The old IBM joystick and Macintosh monitor connector is a DA15. 13W3, as used bu SUN for some monitors, is also a B size. Some companies make 13W3 connectors running gas or liquid lines, or high current power wires through the three holes normally used for coaxial signal cables. Would be pretty neat for a quick connect for a tool turret that needs air along with power and control signals. Two lines for power, one for air, 10 pins for motor control and feedback. https://www.fclane.com/product-group/high-density-combo-d The 19 pin D-Subminiature connector Apple used on Apple // and Macintosh external floppy drives is "That weird-ass connector only Apple used". It has no official letter for its shell size. The guy doing business as "Big Mess O Wires" paid to have a few thousand new ones made to have them for his solid state Apple floppy emulator device, sharing the cost with a couple of parts companies who wanted some of them but couldn't get any due to them all being sold out worldwide. At one point he had the entire world's supply of new 19 pin D-sub connectors on his back porch. Should anyone need more, the company that made them has the tooling to produce them.

Long time no see, been busy working. :) I bought a CNC engraver, really high quality but it has an old Dos(!) PC. Here comes a retrofit! The 60 000 RPM VFD is well documented, the drivers are not. The PC port looks like a parallel port but is labelled 'com 2'. I guess the drivers are step/dir. Anyone with a nice idea how to figure it out? I will try to see if the factory have any manuals left. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
